Maskless, localized aluminum line deposition with 30 $\mu\mathrm{m}$ linewidths is now achievable, driven by a novel direct-write CVD platform that quantifies precursor surface diffusion to predict feature resolution.

Telecom-wavelength quantum memories no longer require difficult direct fabrication in silicon carbide: evanescent coupling through foundry-compatible silicon nanocavities achieves single-photon emission with 109 ns optical lifetimes on a single-fiber interface.
